Answer:
from LHS
sinA/1 + cosA
multiplying by (1 - cosA) on numerator and denominator
sinA ___(1 - cosA)
----------×
1+cosA_(1-cosA)
sinA - sinA×cosA
-----------------------
1² - cos²A
sinA - sinA×cosA
------------------------
sin²A
sin(1-cosA)
---------------
sin²A
1 - cosA
------------
sinA
=> 1/sinA -cosA/sinA
=> cosecA - cotA RHS prooved
